| 摘 要： | 河南汝阳县竹园沟钼矿床是新近发现并探明的斑岩型钼矿床，该矿床最大特点是赋矿岩石全部为花岗岩类岩石。矿床的成矿母岩为中细粒黑云母花岗斑岩，该类岩石常具似斑状结构，说明其成岩是浅成的。根据矿床矿石内各类脉体的先后顺序及含矿性，结合矿物的共生组合关系及结构构造特征，将矿化划分为四个热液作用阶段：即①石英脉阶段；②辉钼矿一石英脉阶段；③辉钼矿一钾长石一石英脉阶段；④萤石一钾长石一石英脉阶段。结论是：第②、③两个阶段是矿床的主要成矿阶段。

| Abstract: | Zhuyuangou molybdenum deposit is a newly discovered and proved porphyry molybdenum deposit in Ruy- ang, Henan. Its most obvious characteristic is that the ore -host rocks are all granite. The metallogenic mother rocks belong to mid - fine grained biotite granite porphyry, and this kind of rock＇ s structure is always similar to that of porphyritic rock, so it proves hypabyssal diagenesis. According to all kinds of veins＇ order and the ore - bearing potential in the deposit, and the combinative relations with mineral association and structure features, min- eralization is divided into four hydrothermal process stages ： （ 1 ） the quartz vein stage ; （2） the molybdenite - quartz vein stage; （3） molybdenite -potassium feldspar- quartz vein stage; （4） the fluorite -potassium feldspar -quartz vein stage. The conclusion is： （2）and （3） are the main mineralization sta~es of the deposit. |
